Make Pocket Code Bricks feature-complete to Scratch

by Andreas Mueller for Catrobat (formerly Catroid Project)

Pocket Code is missing the popular show/hide variable as well as Userbricks(self-defined functions) from scratch. Show and hide variable bricks are necessary to display, e.g., game statistics. Userbricks are used to create self-defined functions. http://wiki.scratch.mit.edu/wiki/Show_Variable_()_(block) http://wiki.scratch.mit.edu/wiki/Define_()_(block)
